PHS1 legacy probe head

  • PHS1 servo positioning headMeets the demanding requirements of "body in white" measurement where fine angular positioning and long reach are needed
  • 2-axis servo operated with a ±184° variable positioning capability in both axes
  • Long reach up to 750 mm (29.53 in) enables trigger probes to measure otherwise inaccessible features
  • Automatic probe changing
  • Repeatable exchange of PHS1 probe heads via KM1 / KM2
  • Easy interchange with Renishaw's PH10T PLUS / PH10M PLUS motorised heads via a PHA1 or PHA2 probe head adaptor in applications where existing parts need to be inspected without the need to re-write the programs for PHS1

System components

PHS1 head

This is not locked into position in the same manner as an indexing head. Instead, it is driven to approximately the required position and when a probing point is taken, the axes of the head latch simultaneously with the axes of the CMM to give accurate probe readings.

The PHS1 head is controlled directly via a PC interface card in the CMM controller, and requires full integration by the equipment supplier. It has an in-built overtravel protection unit that can be configured to stop the machine in the event of a collision.

An air supply to the head is recommended for axis motor cooling and optimum metrology performance.

PHS1 & extension dimensions

PHA adaptors

  • PHA1 is fitted to a PH10M PLUS / PH10T PLUS for rapid mounting to KM1 / KM2
  • PHA2 is fitted to a horizontally installed PH10M PLUS / PH10T PLUS for rapid mounting to KM1 / KM2
  • Enables programming of existing parts without needing to rewrite programs for the PHS1

PHA2

PHS1 kinematic mounts

  • Enable quick fixing of the PHS head to the CMM for fast interchange with other heads
  • KM1 is designed for through quill cabling
  • KM2 is designed for round quill cabling
